Bogie, I'm trying to help you here by pointing you in the right direction. It's not a matter of "what works for me"... it's a matter of what is correct, period.
Unless, of course, your tutorial is ONLY intended for the construction of H2H terrains, and it does not matter if it is built correctly... then you should make a disclaimer on the front page of it. If that is your only intention, then I apologize and will lay back.
In short... Yes, you absolutely assign VHs and Ports as Group Masters, and in the Object Data box you type in 0 for airfield, 1 for VH, and 2 for port. These code numbers provide the correct icons on the map, which is what you were trying to do (incorrectly) by assigning them the VH Type and Port Type.
This is all in the TE Help file.
